Introduction:
Making a quit attempt is a key step in smoking cessation. Intention to quit has been found to be an important factor which associated with quit attempts. Many factors have been shown to be associated with intention to quit such as socioeconomic factors, positive attitude towards quitting, higher self-efficacy and etc. Identifying factors affecting intention to quit would have potential to improve smoking cessation rate.

Objectives:
To examine the correlation of number of smoked cigarette per day and intention to quit.

Methods:
40 daily smokers who participate in smoking cessation program were completing baseline data including number of smoked cigarette per day and intention to quit. Intention to quit was assessed by using 10-cm visual analog scale. The Pearson's correlation was conducted for the correlation test.

Results:
An average intention to quit of 40 daily smokers was 7.8 ± 1.8 and smoked an average of 9.3±5.5 cigarettes per day. 62.8% of participants have never tried to quit smoking. There was a moderate correlation between the number of smoked cigarette per day and intention to quit (r=-0.53, p < 0.00).

Conclusion(s):
Number of smoked cigarette per day was significantly associated with quitting and intention to quit among daily smokers. Thus, smokers who smoked higher puff a day may likely to need more intensive support if they are engaged in smoking cessation program.
